This work presents a novel nonorthogonal multiple access (NOMA) cognitive radio (CR)
system where the base station (BS) opportunistically multiplexes the secondary user (SU) …

The synergy of nonorthogonal multiple access (NOMA) and cognitive radio (CR) can provide
efficient spectrum utilization for future wireless networks and enable supporting …

In this paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …

In this paper, the performance of a multicarrier underlay cognitive radio system is analyzed
considering that the successive interference cancellation (SIC) method is used for detection …

In this paper, cognitive radio (CR) based on non-orthogonal multiple access (NOMA) is
considered over frequency non-selective Rayleigh fading channels. The two techniques are …

In traditional cognitive radio (CR), secondary user (SU) can only access the idle spectrum
when primary user (PU) is absent, which has to vacate the spectrum when detecting the …

In this paper, we demonstrate that despite the power constraints on all transmit nodes
caused by the interference temperature limit (ITL) imposed by the primary user, power …

The paper presents performance analysis of a multiuser Cooperative Non-Orthogonal
Multiple Access (CNOMA) network that is underlay to a primary network. A selected …

This paper investigates the outage performance of secondary users (SUs) in underlay
cognitive radio–based nonorthogonal multiple access (CR‐NOMA) networks. We consider …

Non-orthogonal multiple access (NOMA) and cognitive radio (CR) are envisioned as
promising solutions to achieve high spectral efficiency for future wireless networks. This …
